I have two different networks. I have an internal network that connects my machines to our database. I also have an external network that connects the machines to the internet. The IP Classes for the Internal Network is (10.10.10.1,255.255.255.0) The IP class for the external network is (192.168.2.x,255.255.0.0). The problem is when I have both LAN active I cannot telnet into my database. Once I disable the External LAN I can telnet in fine.Any Ideas?

Well you can't run Two Connection if your run the tow of them it'll be wise if you turn off the other one. Want A Weekly Update on Latest System Security Problem http://www.systemsecurityinstitute.org

I think best thing to do is to "bind" your mysql service to the ip address in the internal network in which it will not be accessible to the internet directly. tho the ip addresses you have given are all private ip addresses. then all your clients or application servers will refer to that binded ip address. -Jahskee

To follow up if you bind mysql service to a specific ip address lets say only to 192.168.2.x and not thru localhost which i think is the default. you dont have to disable any NIC.
